| Diseases of wild jaguars in southeastern Mexico | |
| 2011 Book Chapter | |
Large felids are indicators of ecosystem changes. Recent studies show that infectious diseases have devastating effects in their populations. Furthermore, habitat conversion due to anthropogenic activities has increased incidence of wildlife diseases, therefore, besides ecological data, it is important to identify both, the diseases potentially important to large carnivores, and the ecological conditions associated with their expansion and severity. The seroprevalence of viral, bacterial and parasitic diseases and some hematological parameters were evaluated in wild jaguars from two places of Southern Mexico; the Calakmul Biosphere Reserve and Ejido Caoba. In Ejido Caoba, the seroprevalence of diseases transmitted by domestic carnivores (canine parvovirus/feline panleukopenia) was 8 %, by vectors (feline heart worm) 86.6 %, and by wild reservoirs (Toxoplasma) 55.5 %, while no antibodies were found within the Reserve. Antibodies against Brucella abortus was found in the only male tested in the Reserve, and from one of 8 jaguars in Ejido Caoba (12.5%). Antibodies against feline immunodeficiency virus, feline coronavirus, Chlamydia and feline leukemia were not found. Habitat changes due to the human activities could be responsible for the greater seroprevaence in Ejido Caoba. The hematological parameters of wild jaguars from the Reserve are more similar that the values of captive jaguars, in Ejido Caoba, these values are different from the values of captive jaguars, mainly in the eukocyte formula. |
